Idea: Editing recent address list?

Okay, by this point my Chatter recent address list is riddled with typos and no-longer-used addresses. I know I can wipe the entire list and rebuild it from my contacts lists, but that would blow away all of the manually-typed entries. Maybe, in an ideal world, Chatter could allow manual removal of selected entries from the list? I realize this is probably more than Marc wants to tackle, but I just thought I'd throw it out there.......
